Chinadoll, friendship between the sexes is totally possible, I say this with experience. My best friend at school. for 5 years was a boy (Zain) although he asked me out when we were 11 and I was too paranoid so I said no, and then we became best friends after that (weird, I know).
Although, I was brought up with the same islamic bullcrap as all of you here, "don't talk to boys, don't befriend boys, don't think about boys, don't fucking see a boy" yeah you get it I bet. But clearly i've always been a rebel and well I was a very dateable sort of girl, for obvious reasons
, I dated too many older boys, and this was a reason for many girls at my secondary school to envy me, back chat about me and just plainly hate me.
That would be another reason for why I got on so well with the lads, although I was never the sporty type so no they definitely didn't see me as a buddy. Maybe they were after that one thing too, but I highly doubt it as I never dated any high school boys when I was in high school.
This would probably sound cliche, but what i've found is that most guys that are my friends I end up falling for them cause they're nice enough to be boyfriend material. Does that make much sense?
Sorry for the ramblings..
